Jeff Passan is reporting that Nick Burdi has a strained biceps tendon and flexor mass.
Considering how awful it looked, the preliminary exam on Pirates reliever Nick Burdi is promising: Nothing is fully torn or broken, source tells ESPN. MRI did reveal strained biceps tendon and flexor mass, which will sideline him indefinitely, but diagnosis would mean no surgery.

This sucks, but it’s far from a worse case scenario considering how bad things looked yesterday. Pirates Prospects has a good discussion of the implications, assuming this holds up.
